In this paper, crystalline V 2 O 3 and amorphous V 2 O 3 /C products are synthesized via one-pot solution combustion synthesis (SCS) method (completed within 2 minutes).The characteristics of combustion products could be tuned by changing the amounts of glucose. The as-synthesized crystalline V 2 O 3 nanopowder consists of nanoparticles with average size of ~100 nm. Amorphous V 2 O 3 /C composite exhibits large porous microsheet structure in which oxygen vacancy-enabled amorphous V 2 O 3 particles are embedded into N-doped carbon microsheets. The existence of oxygen vacancies can promote energetics for the transport of electrons and ions and maintain the integrity of sample surface morphology. Moreover, N-doping can enhance electrical conductivity and promote the diffusion of electrons and lithium ions. Amorphous V 2 O 3 /C composite possesses high reversible capacity and superior cycling stability (833 mAh g −1 at 1 A g −1 after 250 cycles, 867 mAh g −1 at 0.1 A g −1 after 100 cycles), indicating its potential as excellent anode material for lithium-ion battery. The proposed one-step, time-and energy-efficient SCS method has the potential to prepare other oxygen vacancy-enabled transition metal oxides for energy storage.

In 2020, energy-related CO2 emissions reached 31.5 Gt, leading to an unprecedented atmospheric CO2 level of 412.5 ppm. Hydrogen blending in natural gas (NG) is a solution for maximizing clean energy utilization and enabling long-distance H2 transport through pipelines. However, insufficient comprehension concerning the combustion characteristics of NG, specifically when blended with a high proportion of hydrogen up to 80%, particularly with minority species, persists. Utilizing the heat flux method at room temperature and 1 atm, this experiment investigated the laminar burning velocities of CH4/NG/H2/air/He flames incorporating minority species, specifically C2H6 and C3H8, within NG. The results point out the regularity of SL enhancement, reaching its maximum at an equivalence ratio of 1.4. Furthermore, the propensity for the enhancement of laminar burning velocity aligned with the observed thermoacoustic oscillation instability during fuel-rich regimes. The experimental findings were contrasted with kinetic simulations, utilizing the GRI 3.0 and San Diego mechanisms to facilitate analysis. The inclusion of H2 augments the chemical reactions within the preheating zone, while the thermal effect from temperature is negligible. Both experimental and simulated results revealed that CH4 and NG with a large proportion of H2 had no difference, no matter whether from a laminar burning velocity or a kinetic analysis aspect.
